EXECUTIVE SUMMARY
The City of Napa’s Local Roadway Safety Plan (LRSP) is a comprehensive plan that creates a framework to systematically identify and analyze traffic safety related issues and recommend projects and countermeasures. It aims to reduce fatal and severe injury collisions through a prioritized list of improvements that can enhance safety on local roadways.
The LRSP takes a proactive approach to addressing safety needs. It is viewed as a guidance document that can be a source of information and ideas. It is also a living document, one that is routinely reviewed and updated by City staff and their safety partners to reflect evolving collision trends and community needs and priorities. With the LRSP as a guide, the City will be able to apply for grant funds, such as the federal Highway Safety Improvement Program (HSIP) or One Bay Area Grant (OBAG). This document summarizes an analysis of collisions that occurred in Napa, identifies high-injury locations, and recommends countermeasures at each of these high-injury locations. It is organized into eight sections as follows:
Chapter 1 –
Introduction
The Introduction describes what an LRSP is and details the study area.
Chapter 2 – Safety Partners
Involvement of safety partners is critical in the success of the LRSP. For the City of Napa, this included a stakeholder group made up of representatives from local governmental and community organizations including City staff from the Public Works Department, Napa Police Department, and Napa Fire Department, and representatives from the City of Napa Bicycle and Trails Advisory Commission, Napa Valley Unified School District, Napa Valley Transportation Authority, Napa Chamber of Commerce, Napa County Bicycle Coalition, Slow Down Napa, Napa Valley Vine Trail Coalition, Visit Napa Valley , and Downtown Napa Association. This chapter summarizes the involvement of the stakeholders in the LRSP process.
Chapter 3 – Existing Planning Efforts
This chapter summarizes City and regional planning documents and projects that are relevant to the LRSP.
It ensures that the recommendations of the LRSP are in line with existing goals, objectives, policies, or projects.
Chapter 4 – Collision Data and Analysis
This chapter summarizes the data analysis approach and presents preliminary as well as detailed collision analysis and findings in the study area. An analysis of fatal and severe injury (F+SI) collisions is performed by facility type (intersection and roadway segment). Collision data was obtained and analyzed for a five- year period from 2016 to 2020 from the California Highway Patrol’s Statewide Integrated Traffic Records

Local Roadway Safety Plan
System (SWITRS) and th e University of California at Berkeley SafeTREC’s Transportation Injury Mapping Service (TIMS).
Chapter 5 – Emphasis Areas
Emphasis areas are a focus of the LRSP that are identified through the various collision types and factors resulting in fatal and severe injury collisions within the City of Napa. The seven emphasis areas for Napa are:
1. Improve Intersection Safety (Collisions within 250 feet of an intersection)
2. Address Rear End Collisions & Unsafe Speed Violations
3. Address Broadside Collisions
4. Improve Pedestrian Safety
5. Address Nighttime Collisions
6. Address Driving Under the Influence (DUI) Collisions
7. Address Young Adult Party-at-Fault Collisions
Chapter 6 – Countermeasure Identification
Engineering countermeasures were selected for each of the high-inju ry locations and for the emphasis areas. These were based off of approved countermeasures from the Caltrans Local Roadway Safety Manual (LRSM) used in HSIP grant calls for projects. The intention is to give the City potential countermeasures for each location that can be implemented either in future HSIP calls for projects, or using other funding sources, such as the City ’s Capital Improvement Program. Non -engineering countermeasures were also selected using the 5 E’s strategies, and are included with the emphasis areas.
Chapter 7 – Safety Projects
A set of six safety projects were created for high-injury intersections and roadway segments, using HSIP approved countermeasures. These safety projects are:
Project #1: Signalized Intersections (Raised Pavement Markers, and Improve Pavement Friction) Project #2: Signalized Intersections (Improve Signal Hardware and Timing, and Advance Warning Flashing Beacon)
Project #3: Signalized Intersections (Modify Signal to include a Leading Pedestrian Interval, Install Advance Stop Bar, and Install Pedestrian Countdown Signal Heads) Project #4: Non-Signalized Intersections (Install High Visibility Crosswalk, Install/Upgrade Larger or Additional STOP Signs or other Intersection Regulatory/Warning Signs, and Improve Intersection Pavement Markings)
EXHIBIT A

Local Roadway Safety Plan
Project #5: Roadway Segments: (Install/Upgrade Signs with Fluorescent Sheeting, Install Delineators/Reflectors/Object Markers, and Improve Pavement Friction) Project 6: Roadway Segments: (Install High Visibility Crosswalks, Install Rectangular Rapid Flashing Beacons, and Install Dynamic/Variable Speed Warning Signs) Chapter 8 – Implementation and Evaluation
The LRSP is a guidance document that is recommended to be updated every two to five years in coordination with the safety partners. The LRSP document provides engineering, education, enforcement, and emergency medical service-related countermeasures that can be implemented throughout the City to reduce fatal and severe injury collisions. After implementing countermeasures, the performance measures for each emphasis area should be evaluated annually. The most important measure of success of the LRSP should be reducing fatal and severe injury collisions throughout the City. If the number of fatal and severe injury collisions does not decrease over time, then the emphasis areas and countermeasures should be re- evaluated.

1. INTRODUCTION
What is an LRSP?
The Local Roadway Safety Plan (LRSP) is a localized data-driven traffic safety plan that provides opportunities to address unique roadway safety needs and reduce the number of fatal and severe injury (F+SI) collisions. The LRSP creates a framework to systematically identify and analyze traffic safety-related issues, and recommend safety projects and countermeasures. It facilitates the development of local agency partnerships and collaboration, resulting in the development of a prioritized list of improvements that can qualify for Highway Safety Improvement Program (HSIP) funding. The LRSP is a proactive approach to addressing safety needs and is viewed as a living document that can be constantly reviewed and revised to reflect evolving trends, and community needs and priorities.
Process
The systemic approach in preparing the LRSP involves the following steps:
Develop plan goals and objectives
Analyze collision data
Meet with stakeholders/safety partners
Determine focus areas and identify crash reduction strategies Prioritize countermeasures/projects
Prepare the LRSP
Study Area
The City of Napa, located in Napa County, California, covers a total area of 18.3 square miles and is located in the Northern Bay Area approximately 50 miles from San Francisco . The City’s estimated population is 79,246 (US Census 2020). SR 29, SR 12, SR 221, and SR 121 are major thoroughfares that connect the city with the rest of Napa County and the Bay Area. The nearest cities include Yountville to the north, Sonoma to the west, American Canyon to the south, and Fairfield to the east. The study area is mapped in Figure 1 below.

Relevant City and County Planning Documents & Projects
Napa General Plan (1998)
Adopted in 1998, the Envision Napa 2020 General Plan formalizes a long-term vision for the physical evolution of Napa and outlines policies, standards, and programs to guide day-to-day decisions concerning Napa’s development. Most relevant to the development of the LRSP is the Circulation element, which focuses on the access and mobility needs of residents and businesses in the City of Napa.
It contains several sections addressing the various modes of transportation in Napa, including: street and roadway system, roadway levels of service and vehicle miles traveled, crucial corridors, residential streets, public transit, bicycle routes, bicycle facilities, bicycle safety, pedestrians, and air/water/rail transport. Future transportation improvements are also outlined in the element, including roadway improvements, future bicycle facilities, and a citywide trails plan.
Downtown Napa Specific Plan (2012)
The Downtown Napa Specific Plan provides the guiding framework for realizing the vision of a vibrant, healthy, and balanced pedestrian oriented city center. The purpose of the Specific Plan is to illustrate and bring to life the community based vision; and create an implementation action plan to systematically achieve its key objectives. It includes a chapter on Circulation and Parking, which provides guidance to improve all forms of transportation serving Downtown. It aims to return the streets of Downtown Napa to its original function of providing access and mobility for transit users, bicyclists, and pedestrians, while balancing the needs of motorists, goods movement, and emergency access.
The Circulation and Parking chapter is divided up into seven sections, primarily focusing on the existing and planned roadway system, transportation systems and demand management, public transit system, pedestrian and bicycle circulation, and parking supply and demand/parking management plan. One of the main recommendations of the plan is to convert one-way couplet streets in Downtown to two-way streets, in order to allow greater access and create less confusion for visitors. Other recommendations include (but are not limited to): an extension of Coombs St, transportation demand management strategies, relocation of Downtown Transit Center, and new bicycle/pedestrian facilities.

City of Napa Bicycle Plan (2021)
Developed as part of the Napa Countywide Bicycle Plan, The City of Napa Bicycle Plan is intended to guide development of infrastructure, programs, and policies that improve the bicycling environment for all residents and visitors in Napa. It is intended to help the City achieve the plan’s vision statement of having Napa County be a bicycle–friendly community with a world-class bicycling system for all ages and abilities, and achieve a 10% mode shift toward bicycling by 2035.
The plan first details the City ’s existing bicycle network, which currently totals 49 miles of Class I, Class II, and Class III facilities. It follows this with a detailed analysis of bicycle collisions, the community input process, proposed bicycle network, and support programs/policies. Included in these support programs and policies are a number of policies in regards to bicycle safety, which will help to inform any recommended countermeasures regarding addressing bicycle collisions. Finally, the recommended bicycle projects are categorized into immediate, short, medium, and long term projects. A total of 59.2 miles of bicycle facilities were recommended.
City of Napa Pedestrian Plan (2017)
The City’s Pedestrian Plan is intended to be a guiding document for maintaining and implementing new pedestrian infrastructure in Napa. It was developed as part of a countywide effort with the Napa Valley Transportation Authority (NVTA) to develop the Napa Countywide Pedestrian Master Plan. The plan first starts with an inventory of existing sidewalks and crosswalks in 12 neighborhoods citywide, pedestrian counts, a collision analysis, and public and stakeholder input. It then identifies opportunity areas that estimates pedestrian demand on streets throughout Napa. High demand areas included the downtown core, Trancas St, Lincoln Ave and Jefferson St near Napa High School, and neighborhood pockets near Phillips Charter School and Imola Ave. The plan concludes with project development and a table of recommended projects, followed by potential funding sources.

Napa Valley Countywide Transportation Plan (2021)
The Advancing Mobility 2045 Countywide Transportation Plan (CTP) outlines priorities for the Napa Valley Transportation Authority and Napa County’s transportation system to relieve congestion, improve traffic safety, create more active transportation infrastructure, provide more reliable and frequent bus service, and maintain and repair the existing transportation system. The CTP is a required planning document that is updated every four to five years with planned transportation projects and funding sources. The plan begins with a section on the vision of the plan and its goals, objectives, and performance metrics. It’s then followed by a summary of existing transportation, land use, and travel patterns/behaviors within the Napa Valley, including information on Communities of Concern in Napa County. This is followed by a section detailing the existing infrastructure, policies, and programs surrounding the roadway system, bicycle/pedestrian, transit, and transportation demand management in Napa County. Of most relevance is a section on Health and Safety, which includes information on safety (including a collisio n analysis), Vision Zero, and Complete Streets. The plan concludes with a list of recommended projects, travel forecasting, and funding sources. 28 projects are recommended within the City of Napa.
Napa Valley Community Based Transportation Plan (2020)
The Napa Valley Community-Based Transportation (CBTP) is the result of a community-based planning effort in Napa County, led by the Napa Valley Transportation Authority. It relies on an open community discussion between residents and transportation planners to identify transportation gaps of low- income and underserved residents in communities of concern. The overarching goal of the CBTP is to identify perceived transportation gaps, provide example projects identified by residents, and provide a list of improvements, such as infrastructure projects or social service programs. An intensive public outreach campaign was undertaken as part of the plan, including 15 outreach meetings.
In this outreach campaign, the second most mentioned comment was to increase pedestrian safety. A total of eight communities of concern were identified countywide, five of which are in Napa. The plan includes a profile of each, including demographic information, commute patterns, and population. A needs analysis for each community was conducted, which partially included an analysis of collisions. From this, a priority need/opportunity was identified for each community. Lastly, the plan concludes with a list of recommended projects/programs and prioritizes CTP projects that can benefit communities of concern.

Imola Avenue Corridor Complete Streets Improvement Plan (2020) Imola Avenue is a major east-west corridor in south Napa that is primarily oriented to auto traffic. The purpose of the Complete Streets Improvement Plan is to articulate the current challenges on the corridor and recommend achievable complete streets solutions to implement the community vision. The study area includes 3.5 miles of Imola Avenue between Foster Road and 4th Avenue, divided into three segments. The plan included a robust community outreach campaign, and details existing conditions, vision and goals for the corridor, corridor strategies, improvement concepts, an evaluation of the proposed concepts, and an implementation plan. As it pertains to the LRSP, the plan will inform any potential countermeasures selected for the Imola Avenue corridor to make sure they fit in with the overall corridor vision.
City of Napa Capital Improvement Program (2021)
The City’s Capital Improvement Program details all capital projects the City has budgeted over the next five fiscal years (until FY 2026). This includes projects pertaining to bicycle/pedestrians, facilities, miscellaneous (eg. parking, EV charging, etc.), parks, sidewalks, storm drains, streets, traffic signals, underground utility, and water administration/distribution. The CIP will inform the LRSP on upcoming projects in the City and ensure that any recommendations complement existing efforts. Looking at project areas relevant to the LRSP, there are a total of two bicycle/pedestrian projects, one sidewalk project, 51 street projects, and three traffic signal projects.
Citywide Guidelines for Traffic Calming and Neighborhood Traffic Management (2005) The City’s traffic calming guidelines provide a framework fo r the potential selection, funding, application, and design of traffic calming measures in the City of Napa in order to support the General Plan policy of “protecting residential neighborhoods from high-volume and high-speed traffic and its effect”. The d ocument outlines policy guidelines of when to consider traffic calming measures, protecting emergency response routes, arterials/collectors, truck routes, and transit access, and the selection and placement of appropriate traffic calming measures. The plan also includes ways to incorporate traffic calming into new street networks, and a self-help neighborhood program for traffic calming. This is followed by a toolbox of traffic calming measures. The traffic calming guidelines are important to the LRSP as it informs it of existing policies and programs to combat speeding in

residential areas within Napa. Traffic calming measures are sometimes recommended as part of an LRSP, though they are typically not eligible for highway safety funding.
City of Napa Standard Plans and Specifications (2022)
The City’s Standard Plans and Specifications lay out the standard practices by which infrastructure is designed and constructed in Napa. The Standard Specifications focuses on general provisions for construction of projects, followed by standard specifications for projects regarding drainage, streets, landscaping, water distribution, signals/lighting/electrical systems, and solid waste/recyclable materials/compost. The LRSP primarily focuses on street, traffic signal, and electrical improvements and as such these sections will be most informative on the LRSP’s recommendations. The Street Standards include design criteria, considerations of driveways/parking facilities, private street connections, fire department access, and street special provisions. The Signals, Lighting, and Electrical Systems section focuses on specifications for (among other things):
signal controller cabinets, controller cabinet equipment, pole standards, heads, and pedestrian push buttons. The Standard Specifications is complemented with the Standard Plans, which provides detailed engineering plans for standard design elements of drainage, storm water, street, fire, parks and landscaping, street trees, water, electrical, and solid waste and recycling projects.
Napa Municipal Code (1992)
The Napa Municipal Code details the laws governing the City of Napa, divided into 17 sections. As it pertains to the LRSP, the most relevant section is Title 10, Vehicles and Traffic. Title 10 details the vehicle code by which motorists, bicyclists, pedestrians, and other modes must move about Napa in a safe and orderly manner. As one of the 4 E’s of traffic safety, enforcement of traffic laws is a key portion of the LRSP and critical to addressing traffic safety. The Municipal Code details the laws that must be followed in order to ensure that all that use the transportation system do so in a way that is safe.

4. COLLISION DATA ANALYSIS
This chapter summarizes the results of the analysis of collisions that have occurred in the City of Napa between January 1, 2016 and December 31, 20 20, as part of the Local Roadway Safety Plan (LRSP). This chapter includes the following sections:
1. Data Collection
2. Collision Data Analysis
3. Fatal and Severe Injury Collision Analysis
4. Geographic Collision Analysis
5. High Injury Network
6. Summary
The LRSP focuses on systemically identifying and analyzing traffic safety issues and recommends appropriate safety improvements. The collision analysis starts with a comprehensive analysis of injury collisions of all severity types in the City of Napa and compares this with fatal and severe Injury ( F+SI) collisions. Factors such as collision severity, type of collision, primary collision factor, lighting, weather, and time of day were analyzed. Following this, a more detailed analysis was conducted for fatal and severe injury ( F+SI) collisions that have occurred on the City ’s roadways, including analyzing collision factors together (such as comparing collision type with violation category). Figure 6 illustrates all the injury collisions (excluding Property Damage Only (PDO) collisions) that have occurred in the City of Napa from 1/1/2016 to 12/31/2020.

Data Collection
Collision data helps to understand different factors that might be leading to collisions and influencing collision patterns in a given area. For the purpose of this analysis, five-years of jurisdiction-wide collision data (2016 to 2020) was retrieved from Transportation Injury Mapping System (TIMS) and Statewide Integrated Traffic Records System (SWITRS). Collisions that occurred on the freeway portions of SR 29 (roughly Imola Ave to Trancas St) were not included in the analysis. Collisions on other state routes (SR 12, SR 29 non-freeway, SR 121, and SR 221) were included. The collision data was analyzed and plotted in ArcMap to identify high-injury intersections and roadways segments.
Collision Data Analysis
Collision Analysis by Severity
There were a total of 1,207 collisions reported on
the City of Napa roads from 2016 to 2020. Out of
these, 721 collisions (60%) led to complaint of pain
injury and 406 collisions (34%) led to a visible injury.
There were 80 F+SI (fatal and severe injury) collisions, of which 68 collisions (5%) led to a severe injury and
12 collisions (1%) led to a fatality. Figure 7 illustrates the classification of all collisions based on severity.
The analysis first includes a comparative evaluation
between all collisions and F+SI collisions, based on
various factors including (but not limited to): collision trend, primary collision factor, collision type, facility type, motor vehicle involved with, weather, lighting, and time of the day. Following this, a comprehensive analysis is conducted for only F+SI collisions. F+SI collisions cause the most damage to those affected and to infrastructure. The aftermath of these collisions can lead to great expenses for jurisdiction administration. The LRSP process thus focuses on these collision locations to proactively identify and counter safety issues leading to these F+SI collisions.
The collision data was separated by facility type, i.e. based on collisions occurring on intersections and roadway segments. For the purposes of the analysis and in accordance with HSIP guidelines, a collision was designated to have occurred at an intersection if it occurred within 250 feet of it. The reported collisions categorized by facility type and collision severity are presented in Table 2.

Yearly Trend
The number of reported collisions of all severity has overall decreased between 2016 and 2020, with an increase from 2017 to 2019. The year with the highest number of collisions was 2019 (293 collisions), while the year with the lowest number of collisions was 2020 (207 collisions). A total of 80 F+SI collisions occurred in the City of Napa during the study period, overall consistent from 2016 to 2020. The least number of F+SI collisions occurred in 2016 (13 collisions), while the most occurred in 2020 (18 collisions).

Roadway Segment vs. Intersection
When evaluating the locations of collisions, most collisions occurred at intersections and not along roadway segments. In the City of Napa, 90% of all collisions (1,082 collisions) occurred at intersections whereas 10% (125 collisions) occurred on roadway segments. A slightly stronger trend towards intersection collisions is seen when looking only at F+SI collisions. This classification by facility type can be observed in Figure 9.
Figure 9: Roadway Segment vs. Intersection: All Injury Collisions vs. F+SI Collisions
Collision Type
For collisions of all severity, the most commonly occurring collision type was broadside collisions (40%) and rear end collisions (26%). The collision types for F+SI collisions follow a different pattern, where the most commonly occurring collision type was vehicle/pedestrian collisions (30%), broadside collisions (24%) and hit object (15%). Figure 10 illustrates the collision type for all collisions as well as F+SI collisions.

Geographic Collision Analysis
This section describes a detailed geographic collision analysis performed for injury collisions occurring on roadway segments and at intersections in the City of Napa. The above collision analysis was used to identify five main collision factors that highlight the top trends among collisions in the City of Napa. These five collision factors were identified to be broadside collisions, nighttime collisions, unsafe speed violations, DUI violations, and pedestrian collisions.
Broadside Collisions
Broadside collisions represented the highest proportion of collisions of all severity (40%), and a significant percentage of F+SI collisions (24%). Figure 27 shows the distribution of broadside collisions throughout the City of Napa between 2016 and 2020. Jefferson St, Trancas St, Solano Ave, and Soscol Ave have a higher concentration of broadside collisions.
Nighttime Collisions
Collisions occurring at night represented only 27% of all injury collisions, but rose significantly to 47% of F+SI collisions, indicating that lighting may be a factor in those collisions. Figure 28 shows the distribution of nighttime collisions throughout the City of Napa between 2016 and 2020. SR 29, W. Imola Ave, 3 rd St, SR 12, and Trancas St have a higher concentration of nighttime collisions.
Unsafe Speed Violations
22% of all injury collisions in Napa were caused by unsafe speed, the highest of any violation type among all injury collisions. Figure 29 shows the distribution of unsafe speed collisions throughout the City of Napa between 2016 and 2020. SR 29, W. Imola Ave, Jefferson St, Lincoln Ave, and Soscol Ave have a higher concentration of unsafe speed collisions.
DUI Violations
DUI violations caused only 10% of all injury collisions, but doubled to 20% when considering only F+SI collisions. It was the most common violation type among F+SI collisions. Figure 30 shows the distribution of DUI collisions throughout the City of Napa between 2016 and 2020. Jefferson St, Silverado Trail, and SR 29 have a higher concentration of DUI collisions.
Pedestrian Collisions
Vehicle/pedestrian collisions accounted for 30% of all F+SI collisions (the most of any category), compared to just 9% of all injury collisions. Figure 31 shows the distribution of pedestrian collisions throughout the City of Napa between 2016 and 2020. 3 rd St, Main St, Solano Ave, and Trancas St have a higher concentration of pedestrian collisions, compared to other Napa roads.

The following figures detail concentrations of each of the above five collision factors on roadways throughout Napa. All collisions, whether they occurred at an intersection or roadway segment, are considered in these maps (for example, roads where a particular collision factor is more concentrated may have collisions that occurred at an intersection within the segment, or along the segment itself away from an intersection).

High Injury Network
Collision Severity Weight
Equivalent Property Damage Only (EPDO) method was used to identify the high injury network. The EPDO method accounts for both the severity and frequency of collisions by converting each collision to an equivalent number of property damage only (PDO) collisions. The EPDO method assigns a crash cost and score to each collision according to the severity of the crash weighted by the comprehensive crash cost.
These EPDO scores are calculated using a simplified version of the comprehensive crash costs per HSIP Cycle 10 application. The weights used in the analysis are shown below in Table 3.
Table 3. EPDO Score used in HSIP Cycle 10
Collision Severity EPDO Score
Fatal and Severe Injury Combined 165*
Visible Injury 11
Possible Injury 6
PDO 1
*This is the score used in HSIP Cycle 10 for collisions on roadways segments, to simplify the analysis this study uses the same score for all F+SI collisions regardless of location.
EPDO is used because it provides a methodology for the project team to understand the locations in Napa that are experiencing the most severe crashes. Because of the high score given to fatal and severe injury crashes, locations that have these types of crashes are more likely to receive a higher EPDO score than other locations that may have more collisions, but fewer fatal or severe injury collisions. Locations that have the highest EPDO scores are selected for inclusion in the High Injury Network, shown in the next section.
Identified intersections are scored based on collisions occurring at or within 250 feet of the intersection, while roadway segment locations are identified based on collisions that occur along the segment, except directly at an intersection (0 feet from intersection per SWITRS and TIMS data). Identifying the locations with the most severe crashes allows the team to focus recommended solutions and countermeasures at these locations.
The EPDO scores for all collisions can then be aggregated in a variety of ways to identify collision patterns, such as location hot-spots. The weighted collisions for the City of Napa were geolocated onto Napa’s road network. GIS is then used to calculate the EPDO score for each roadway segment and intersection citywide, which is then ranked according to its score. Figure 32 shows the location and geographic concentration of all collisions (those that occurred at intersections and along roadway segments) by their EPDO score.

High Injury Network
Following the detailed collision analysis, the next step was to identify the high-injury roadway segments and intersections in Napa. The methodology for scoring the high injury locations is the same method as used in the collision severity weight section. Figure 33 shows the top 11 high-injury roadway segments, and top 12 high-injury intersections.
For the purposes of the high injury network analysis, intersections include collisions that occurred within 250 feet of it, and roadway segments include all collisions that occurred along the roadway except for collisions that occurred directly at an intersection. Such collisions are assigned a 0 value in distance from intersection value column in the Statewide Integrated Traffic Records System (SWITRS).

Summary
Between 2016 and 2020, a total of 1,207 injury collisions occurred within the City of Napa, of which 80 resulted in a fatality or severe injury. Among all collisions, the most prominent collision types were broadside and rear end collisions, while unsafe speed and automobile right-of-way were the most common violation types. The corridor with the greatest number of F+SI collisions was Soscol Ave between W. Imola Ave and Trancas St, while the intersection with the most F+SI collisions was Soscol Ave at W. Imola Ave.
Five prominent collision factors that emerged were: broadside collisions, nighttime collisions, unsafe speed violations, DUI violations, and pedestrian collisions. Each of these is described in turn.
Broadside collisions represented the highest proportion of collisions of all severity (40%), a significant percentage of F+SI collisions (24%). Higher numbers of broadside collisions were observed on Jefferson St, Trancas St, Solano Ave, and Soscol Ave, compared to other Napa roads. Broadside collisions can potentially be mitigated by increasing the visibility of an intersection through updated pavement markings, new or updated signage, lighting, advance flashing beacons, and improving sight distance.
Collisions occurring at night represented only 27% of all injury collisions, but rose significantly to 47% of F+SI collisions. Higher numbers of these collisions occurred on SR 29, W. Imola Ave, 3 rd St, SR 12, and Trancas St, indicating lighting as a potential countermeasure at these locations. Many different factors can contribute to nighttime collisions, such as low lighting levels that can be targeted with countermeasure, but extraneous factors can also contribute to nighttime injury such as alcohol use or sleepiness/fatigue.
Improvements such as installing new lighting, upgrading existing lighting to a higher lumen, installing and upgrade signs with new fluorescent sheeting and installing pedestrian improvements with lighting elements such as rectangular rapid flashing beacons (RR FB), pedestrian hybrid beacons or high intensity activated crosswalk beacons (HAWK) can help make these locations safer for all road users. 22% of all injury collisions in Napa were caused by unsafe speed, the highest of any violation type among all injury collisions. Higher numbers of these collisions were experienced on SR 29, W. Imola Ave, Jefferson St, Lincoln Ave, and Soscol Ave. Speeding can be mitigated through the introduction of traffic calming, which can be a combination of street narrowing, medians, bulb outs at intersections, or Complete Streets elements like high visibility crosswalks, bike lanes, and wider sidewalks. Driver education and speed enforcement, either through radar trailers or officer patrols, can also help to mitigate instances of unsafe speed violations.
DUI violations caused only 10% of all injury collisions, but doubled to 20% when considering only F+SI collisions. It was the most common violation type among F+SI collisions. Higher numbers of DUI collisions occurred on Jefferson St, Silverado Trail, and SR 29. Engineering countermeasures can potentially include edge line rumble strips, object markers, guard rails, or ensuring a clear recovery zone. DUI collisions can be addressed with education and enforcement strategies such as DUI checkpoints and educational campaigns on the dangers of impaired driving.

Vehicle/pedestrian collisions accounted for 30% of all F+SI collisions (the most of any category), compared to just 9% of all injury collisions. Higher concentration of pedestrian collisions occurred on 3rd St, Main St, Solano Ave, and Trancas St. Addressing these types of collisions helps to make Napa’s transportation network safe for all modes of travel. Countermeasures such as traffic calming, high visibility crosswalks, Rectangular Rapid Flashing Beacons (RRFBs), sidewalk bulb outs, advanced flashing warning signs, can all help to address pedestrian collisions.

5. EMPHASIS AREAS
Emphasis areas are focus areas for the LRSP that are identified through the comprehensive collision analysis of the identified high injury locations within the City of Napa. Emphasis areas help in identifying appropriate safety strategies and countermeasures with the greatest potential to reduce collisions occurring at these high injury locations. They can include (but not be limited to): specific collision types, human behaviors, facility types, and specific locations or corridors.
This chapter summarizes the top seven (7) emphasis areas identified for the City of Napa. These emphasis areas were derived from the consolidated high injury collision database ( Appendix B) where top injury factors were identified by combining the data manually. Along with findings from the data analysis, stakeholder and community input was also considered while identifying emphasis areas specific to the City of Napa.
The identified emphasis areas are as follows:
1. Improve Intersection Safety (Collisions within 250 feet of an intersection)
2. Address Rear End Collisions & Unsafe Speed Violations
3. Address Broadside Collisions
4. Improve Pedestrian Safety
5. Address Nighttime Collisions
6. Address Driving Under the Influence (DUI) Collisions
7. Address Young Adult Party-at-Fault Collisions
The 4 E's of Traffic Safety
The LRSP utilizes a comprehensive approach to safety incorporating the “4 E’s of traffic safety”: Engineering, Enforcement, Education, and Emergency Medical Services (EMS). This approach recognizes that not all locations can be addressed solely by infrastructure improvements. Incorporating the 4 E’s of traffic safety is often required to ensure successful implementation of significant safety improvements and reduce the severity and frequency of collisions throughout a jurisdiction.
Some of the common violation types that may require a comprehensive approach are speeding, failure- to-yield to pedestrians, red light running, aggressive driving, failure to wear safety belts, distracted driving, and driving while impaired. When locations are identified as having these types of violations, coordination with the appropriate law enforcement agencies is needed to arrange visible targeted enforcement to reduce the potential for future driving violations and related crashes and injuries.
To improve safety, education efforts can be used to supplement enforcement and improve the efficiency of each strategy. Education can also be employed in the short-term to address high collision locations until the recommended infrastructure project can be implemented. Similarly, Emergency Medical Services entails strategies around supporting organizations that provide rapid response and care when responding to collisions causing injury, by stabilizing victims and transporting them to medical facilities.

Factors Considered in the Determination of Emphasis Areas This section presents collision data analysis findings of collision types, factors, facility types, roadway geometries, and party level data analyzed for the various emphasis areas. Emphasis areas were determined by factors that led to the highest amount of injury collisions, with a specific emphasis on fatal and severe (F+SI) injury collisions. The City of Napa experienced a total of 333 collisions at high injury network locations during the 2016-2020 study period, including 30 F+SI collisions. The data presented below in each emphasis area is based on these collisions.
Each emphasis area is accompanied by comprehensive programs, policies, and countermeasures to reduce collisions on City roads in that specific emphasis area. It provides the basis by which the countermeasure toolbox was developed for each identified high injury location.
Note: Engineering countermeasures are based on the Caltrans Local Roadway Safety Manual and are used in Highway Safety Improvement Program (HSIP) calls for projects. They are categorized as follows:
S = Signalized Intersections Countermeasures
NS = Non-Signalized Intersections Countermeasures
R = Roadway Segments Countermeasures

6. COUNTERMEASURE SELECTION
Identification of Countermeasures
Upon the identification of high-injury locations and Emphasis Areas, the next step was to identify appropriate safety countermeasures. The Caltrans Local Roadway Safety Manual (LRSM) provides 82 countermeasures, of which 21 are eligible in the current Highway Safety Improvement Program (HSIP) call for signalized intersections, 23 for un-signalized intersections, and 38 for roadway segments. The LRSM provides guidance on where to apply the countermeasures including the crash types each countermeasure would address, and a Crash Reduction Factor (CRF) for each countermeasure. The Federal Highway Administration (FHWA) Crash Modification Factors Clearinghouse and published research papers were reviewed by the project team to gain additional insight on CRFs and effectiveness of specific countermeasures.
The project team conducted a thorough review of the high-injury locations (intersections and roadway segments) using aerial photography, Google Maps Street View software, and in-person site visits. Crash characteristics of all collisions occurring on the High Injury Network were considered. After combining the physical and collision characteristics, the project team developed a table of preliminary countermeasures that address each of the seven identified emphasis areas. The table was refined by selecting up to four countermeasures for each high-injury location that were most commonly recommended among all Emphasis Areas. By doing this, the project team was able to identify countermeasures with the greatest opportunity for systemic implementation.
Countermeasure Toolbox
Engineering countermeasures were selected for each of the high-injury locations and for the emphasis areas. These were based off of approved countermeasures from the Caltrans Local Roadway Safety Manual (LRSM) used in HSIP grant calls for projects. The intention is to give the City potential countermeasures for each location that can be implemented either in future HSIP calls for projects, or using other funding sources. Non-engineering countermeasures were also selected using the 4 E’s strategies, and are included with the emphasis areas. The countermeasure toolbox in Appendix C details the draft countermeasures for each high-injury location and emphasis area, separated by intersections and roadway segments. While not all of these countermeasures will be included in the resulting safety projects, they are included to give the City a toolbox for implementing future safety improvements through other means, such as other grant funding sources or the City’s Capital Improvement Program.
Table 14 provides a description of each countermeasure along with the crash reduction factor (CRF), federal funding eligibility, and opportunity for systemic implementation. An excerpt of the LRSM, detailing each available HSIP countermeasure referenced in the recommendations tables, is included as Appendix D.

7. VIABLE SAFETY PROJECTS
This chapter summarizes the process of selecting safety projects as part of the analysis for the Napa Local Roadway Safety Plan (LRSP). The next step after the identification of high-injury locations, emphasis areas and applicable countermeasures was to identify location specific safety improvements for all high-injury roadway segments and intersections.
Specific countermeasures and improvements were selected from the 2022 Local Roadway Safety Manual (LRSM) from Caltrans, where:
S refers to improvements at signalized locations,
NS refers to improvements at non-signalized locations, and R refers to improvements at roadway segments.
The corresponding number refers to the countermeasure number in the LRSM (2022). The countermeasures were grouped into safety projects for high-injury intersections and roadway segments. A total of six safety projects were developed. All countermeasures were identified based on the technical teams’ assessment of viability that consisted of extensive analysis, observations, City staff input, and stakeholder/community input. The most applicable and appropriate countermeasures as identified have been grouped together to form projects that can help make high-injury locations safer.
Table 15 lists the safety projects for high-injury intersections and roadway segments, along with total base planning level cost (2022 dollar amounts) estimates and the resultant preliminary Benefit-Cost (B/C) Ratio.
The “Total Benefit” estimates were calculated for the proposed improvements being evaluated in the proactive safety analysis. This “Total Benefit” is divided by the “Total Cost per Location” estimates for the proposed improvements, giving the resultant B/C Ratio. The B/C Ratio Calculation follows the methodology as mentioned in the LRSM (2022).
Appendix E lists the detailed methodology to calculate B/C Ratio, as well as the complete cost, benefit and B/C Ratio calculation spreadsheet.
These safety projects were chosen based on the previously completed collisions analysis, which was used to identify main collision attributes that were found to be leading factors of fatal and severe collisions in Napa. These collision factors are shown below, as well as viable safety projects that can help address these factors.
Broadside Collisions: Broadside collisions represented the highest proportion of collisions of all severity (40%), a significant percentage of F+SI collisions (24%). Viable safety projects to help address these collisions include improving signal hardware & timing, installing raised pavement markers, improving pavement friction, installing/upgrading larger stop signs or other intersection regulatory/warning signs, and installing flashing beacons as advance warning.
EXHIBIT A
71 City of Napa
Local Roadway Safety Plan
Nighttime Collisions: Collisions occurring at night represented only 27% of all injury collisions, but rose significantly to 47% of F+SI collisions. Viable safety projects to help address these collisions include installing advance warning flashing beacons, installing additional or larger warning/regulatory signs, upgrading signs with new fluorescent sheeting, installing raised pavement markers, installing high visibility crosswalks and Rectangular Rapid Flashing Beacons, and installing delineators/reflectors/object markers.
Unsafe Speed Collisions: 22% of all injury collisions in Napa were caused by unsafe speed, the highest of any violation type among all injury collisions. Viable safety projects to help address these collisions include installing advance warning flashing beacons, upgrading/installing additional stop signs or other intersection warning signs; installing dynamic/variable speed warning signs; and improving pavement friction.
Pedestrian Collisions: Vehicle/pedestrian collisions accounted for 30% of all F+SI collisions (the most of any category), compared to just 9% of all injury collisions. Safety projects to address these include installing a leading pedestrian interval (LPI) at signalized intersections, installing high visibility crosswalks, and Rectangular Rapid Flashing Beacons.
DUI Collisions: DUI violations caused only 10% of all injury collisions, but doubled to 20% when considering only F+SI collisions. It was the most common violation type among F+SI collisions. Viable safety projects to help address these collisions include advance warning flashing beacons, upgrading/installing signs with new fluorescent sheeting, installing delineators, reflectors, or object markers, installing larger or additional stop or regulatory/warning signs, improving signal hardware & timing, and installing raised pavement markings.
Table 15 provides the list of identified safety projects for the City of Napa, with a preliminary cost estimate for each location and the resulting benefit-cost ratio of the project (the title of each countermeasure is located in a separate table below). Following this, the safety projects are also organized by location in Table
16. The manner in which the projects are organized, the inclusion of preliminary cost estimates, and the inclusion of resulting benefit-cost ratios for each project aligns with the requirements for Highway Safety Improvement Program (HSIP) project applications. The safety projects included in the LRSP were based on high-injury locations, but HSIP applications can be expanded to include many locations across the City .
Additional locations may be beneficial to add to the HSIP application, however it should be noted that HSIP is a competitive grant funding source based on a benefit/cost analysis. The benefit value is calculated automatically based on crash data document by law enforcement and standard cost data. The cost of some measures may adversely impact the benefit to cost ratio making the grant application less competitive for funding. This should be taken into consideration when developing an HSIP application.

8. IMPLEMENTATION AND EVALUATION
This chapter describes the steps the City may take to evaluate the success of this plan and steps needed to update the plan in the future. The LRSP is a guidance document and requires periodic updates to assess its efficacy and re-evaluate potential solutions. It is recommended to update the plan every two to five years in coordination with the identified safety partners. This document was developed based on community needs, stakeholder input, and collision analysis conducted to identify priority emphasis areas throughout the City. The implementation of strategies under each emphasis area would aim to reduce F+SI collisions in the coming years.
Implementation
The LRSP is a guidance document that is recommended to be updated every two to five years in coordination with the safety partners. The LRSP document provides engineering, education, enforcement, and emergency medical service-related countermeasures that can be implemented throughout the City to reduce F+SI collisions. It is recommended that the City of Napa implement the selected projects in high- collision locations in coordination with other projects proposed for the City ’s infrastructure development in their future Capital Improvement Plans. After implementing countermeasures, the performance measures for each emphasis area should be evaluated annually. The most important measure of success of the LRSP should be reducing F+SI collisions throughout the City. If the number of F+SI collisions does not decrease over time, then the emphasis areas and countermeasures should be re-evaluated.
Funding is a critical component of implementing any safety project. While the HSIP program is a common source of funding for safety projects, there are numerous other funding sources that could be pursued for such projects. A list of potential funding sources is included in Table 17.

Monitoring and Evaluation
For the success of the LRSP, it is crucial to monitor and evaluate the five E-strategies continuously.
Monitoring and evaluation help provide accountability, ensures the effectiveness of the countermeasures for each emphasis area, and help in making decisions on the need for new strategies. The process would help the City make informed decisions regarding the implementation plan’s progress and accordingly, update the goals and objectives of the plan.
After implementing countermeasures, the strategies should be evaluated annually as per their performance measures. The evaluation should be recorded in a before-after study to validate the effectiveness of each countermeasure as per the following observations:
Number of F+SI collisions
Number of police citations
Number of public comments and concerns
Evaluation should be conducted during similar time periods and durations each year. The most important measure of success of the LRSP should be reduction in F+SI collisions throughout the City. If the number of F+SI collisions doesn’t decrease initially, then the countermeasures should be evaluated as per the other observations, as mentioned above. The effectiveness of the countermeasures should be compared to the goals for each emphasis area.
LRSP Update
The LRSP is a guidance document and is recommended to be updated every two to five years after adoption. After monitoring performance measures focused on the status and progress of the 4 E’s strategies in each emphasis area, the next LRSP update can be tailored to resolve any continuing safety problems. An annual stakeholder meeting with the safety partners is also recommended to discuss the progress for each emphasis area and oversee the implementation plan. The document should then be updated as per the latest collision data, emerging trends, and the E’s strategies’ progress and implementation.

Supplemental Programs and Activities
Supplemental programs and activities can assist in the implementation of the Local Roadway Safety Plan and help to improve safety and reduce F+SI collisions throughout the City. Supplemental work can be completed that addresses the 4 E’s of traffic safety. The following are areas in which supplemental work would support the implementation of the City’s Local Roadway safety Plan:
Vision Zero
Vision Zero is a strategy to eliminate all traffic fatalities and severe injuries, while increasing safe, healthy, equitable mobility of all. At a regional level, the Metropolitan Transportation Commission (MTC) Regional Safety/Vision Zero Policy establishes a strategy for working with partner agencies to support equitable and data-driven action towards eliminating traffic deaths and serious vehicular injuries in the Bay Area by 2030. The regional strategy encourages the adoption of Vision Zero plans and safety best practices at the local level. Adoption of a local Vision Zero policy or plan would support the implementation of the Local Roadway Safety Plan.
Red Light Cameras
A Red Light Camera Program can supplement an LRSP in the 4 E’s area of enforcement. There is evidence that as part of an overall traffic safety plan, red light cameras contribute to an increase in traffic safety citywide. An IIHS study comparing large cities with red light cameras to those without found the devices reduce the fatal red light violation crash rate by 21 percent and the rate of all types of fatal crashes at signalized intersections by 14 percent. The City of Napa previously had red light cameras from 2009 to 2017, and during their time in use, they were successful in reducing injury crashes and crashes overall. In October 2021, the City Council directed staff to look into the impacts of adding back in a red light camera enforcement program. In May 2022, the City Council directed staff to issue a competitive request for proposals (RFP) to select a vendor to provide a red-light camera enforcement program, and return to City Council at a future meeting to consider approving a contract to implement the program.
Traffic Calming
The Local Roadway Safety Plan emphasizes countermeasures to reduce fatal and severe injury collisions at high injury locations, which tend to occur along State Highway and arterial roadways. Based on community input and feedback there is a strong desire to address speeding and increase safety among residential streets and neighborhoods that may not be highlighted as heavily in the LRSP. To help address this community desire and to support the LRSP, the City will be undertaking a Neighborhood Traffic Calming Program. This work will include a series of community workshops, a review and update of the City’s existing traffic calming guidelines, and development of a list of traffic calming strategies. This work will begin in 2022 with anticipated completion in the first half of 2023.

Downtown Napa
Specific Plan (2012)
OVERARCHING TRANSPORTATION AND PARKING POLICIES
1. Ensure the Downtown’s transportation system is designed to enable comprehensive, integrated, safe access for users of all ages and abilities including pedestrians, bicyclists, motorists, transit riders and operators, emergency personnel, and truck operators.
2. Re-establish the Downtown’s historic block pattern and street grid by re-opening street closures when large blocks undergo redevelopment.
3. Convert existing one-way couplets of First and Second streets, and Third and Fourth streets, to t wo-way travel. Establish the conversion among the first capital projects implemented.
4. Re-establish vehicular travel on Coombs Street by converting the existing Coombs Street Plaza to a one -way, northbound street in the short term, two-ways in the long term, for vehicular travel between First Street and Pearl Street. This improvement
EXHIBIT A
4 Document Relevant Goals, Policies, and Projects
significantly enhances vehicular circulation through Downtown and improves access to the Pearl Street parking structure from First Street.
5. Maintain all streets within Downtown a t their current number of lanes, or fewer. Allow minor widening of right -of-way only to facilitate pedestrian and other non -auto- oriented mobility efforts, or as necessary to safely accommodate the appropriate emergency vehicles, trucks or buses.
6. Maintain the economic vitality of the downtown retail and entertainment uses by maintaining sufficient access and loading areas for commercial delivery vehicles.
7. Utilize Transportation Systems Management strategies and technology applications (i.e., traffic signal synchronization) within Downtown to maximize the effectiveness of existing transportation facilities rather than widening roadways or other expansion of facilities
8. Utilize Transportation Demand Management strategies to reduce drive-alone automobile traffic by encouraging travel by carpool, transit, bicycling or walking. Transportation Demand Management programs apply to commercial and residential uses and include incentives and strategies for promoting carpooling, transit use, bicycling and other alternati ve travel modes.
9. Increase transit ridership and reduce automobile travel through appropriate land use planning, improved access to transit and exploration of new transit technologies.
10. Improve pedestrian and bicycle linkages and safety throughout Downtown, and expand the system for recreation and
transportation for all ages by implementing a network of multi- use trails and on-street bicycle connections within Downtown’s greenbelts and waterways, and connecting to the
regional/citywide network. Ensure that ea st-west and north - south routes are provided through Downtown to facilitate access to key destinations for pedestrians and bicyclists of all abilities.
11. Utilize public and private development opportunities to implement public streetscape and open space impro vements to expand and connect to the network of pedestrian -friendly sidewalks, promenades, plazas, paseos and courtyards into and through development projects.
12. Manage parking resources in Downtown to ensure efficiency, encourage pedestrian activity, reduce development costs and
EXHIBIT A
5 Document Relevant Goals, Policies, and Projects
improve the feasibility of developing smaller properties.
Management of parking resources should be maximized prior to construction of new parking facilities.
13. Encourage a “park once” philosophy, where employees and customers can park in one location and visit many destinations within a walkable distance, to reduce vehicle trips within Downtown. Ensure this approach is practical and convenient through high-quality pedestrian facilities and amenities.

1 S01 Add intersection lighting Provision of lighting at intersection. 40% 100% Medium 2 S02 Improve signal hardware: lenses, back-plates with retroreflective borders, mounting, size, and Includes New LED lighting, signal back plates, retro-reflective tape outlining the back plates, or visors to increase signal visibility, larger signal heads, relocation of the signal heads, or additional signal heads. 15% 100% Very High 3 S03 Improve signal timing (coordination, phases, red, yellow, or operation) Includes adding phases, lengthening clearance intervals, eliminating or restricting higher-risk movements, and coordinating signals at multiple locations. 15% 50% Very High 4 S04 Provide Advanced Dilemma Zone Detection for high speed approaches The Advanced Dilemma-Zone Detection system enhances safety at signalized intersections by modifying traffic control signal timing to reduce the number of drivers that may have difficulty deciding whether to stop or proceed during a yellow phase. 40% 100% High
5 S05 Install emergency vehicle pre-emption systems
Corridors that have a history of crashes involving emergency response vehicles. The target of this strategy is signalized intersections where normal traffic operations impede emergency vehicles and where traffic conditions create a potential for conflicts between emergency and nonemergency vehicles. These conflicts could lead to almost any type of crash, due to the potential for erratic maneuvers of vehicles moving out of the paths of emergency vehicles 70% 100% High
6 S06 Install left-turn lane and add turn phase (signal has no left-turn lane or phase before) Intersections that do not currently have a left turn lane or a related left-turn phase that are experiencing a large number of crashes. Many intersection safety problems can be traced to difficulties in accommodating left-turning vehicles, in particular where there is currently no accommodation for left turning traffic. A key strategy for minimizing collisions related to left-turning vehicles (angle, rear-end, sideswipe) is to provide exclusive left-turn lanes and the appropriate signal phasing, particularly on high-volume and high-speed major-road approaches. 55% 90% Low 7 S07 Provide protected left turn phase (left turn lane already exists) Left turns are widely recognized as the highest-risk movements at signalized intersections. Providing Protected left-turn phases for signalized intersections with existing left turn pockets significantly improve the safety for left- turn maneuvers by removing the need for the drivers to navigate through gaps in oncoming/opposing through vehicles 30% 100% High
8 S08 Convert signal to mast arm (from pedestal-mounted) Providing better visibility of intersection signs and signals aids the drivers’ advance perception of the upcoming intersection. Visibility and clarity of the signal should be improved without creating additional confusion or distraction for drivers. 30% 100% Medium
9 S09 Install raised pavement markers and striping (Through Intersection) Adding clear pavement markings can guide motorists through complex intersections. When drivers approach and traverse through complex intersections, drivers may be required to perform unusual or unexpected maneuvers 10% 100% Very High 10 S10 Install flashing beacons as advance warning (S.I.) Increased driver awareness of an approaching signalized intersection and an increase in the driver's time to react. 30% 100% Medium 11 S11 Improve pavement friction (High Friction Surface Treatments) Improving the skid resistance at locations with high frequencies of wet road crashes and/or failure to stop crashes 55% 100% Medium 12 S12 Install raised median on approaches (S.I.) Raised medians next to left turn lanes at intersections offer a cost effective means for reducing crashes and improving operations at higher volume intersections
25% 90% Medium
13 S13PB Install pedestrian median fencing on approaches Signalized Intersections with high pedestrian-generators nearby (e.g. transit stops) may experience a high volumes of pedestrians J-walking across the travel lanes at mid-block locations instead of walking to the intersection and waiting to cross during the walk-phase. 30% 90% Low 14 S14 Create directional median openings to allow (and restrict) left-turns and U-turns (S.I.) Crashes related to turning maneuvers include angle, rear-end, pedestrian, and sideswipe (involving opposing left turns) type crashes. If any of these crash types are an issue at an intersection, restriction or elimination of the turning maneuver may be the best way to improve the safety of the intersection 50% 90% Medium 15 S15 Reduced Left-Turn Conflict Intersections (S.I.)
Reduced left-turn conflict intersections are geometric designs that alter how left-turn movements occur in order to simplify decisions and minimize the potential for related crashes. Two highly effective designs that rely on U- turns to complete certain left-turn movements are known as the restricted crossing U-turn (RCUT) and the median U-turn (MUT). 50% 90% Medium
16 S16 Convert intersection to roundabout (from signal) Signalized intersections that have a significant crash problem and the only alternative is to change the nature of the intersection itself. Roundabouts can also be very effective at intersections with complex geometry and intersections with frequent left-turn movements. Varies 100% Low 17 S17PB Install pedestrian countdown signal heads Signals that have signalized pedestrian crossing with walk/don't walk indicators and where there have been pedestrian vs. vehicle crashes.
25% 100% Very High
18 S18PB Install pedestrian crossing (S.I.)
Signalized Intersections with no marked crossing and pedestrian signal heads, where pedestrians are known to be crossing intersections that involve significant turning movements. They are especially important at intersections with (1) multiphase traffic signals, such as left-turn arrows and split phases, (2) school crossings, and (3) double- right or double-left turns. At signalized intersections, pedestrian crossings are often safer when the left turns have protected phases that do not overlap the pedestrian walk phase. 25% 100% High 19 S19PB Pedestrian Scramble
Pedestrian Scramble is a form of pedestrian "WALK" phase at a signalized intersection in which all vehicular traffic is required to stop, allowing pedestrians/bicyclists to safely cross through the intersection in any direction, including diagonally. Pedestrian Scramble may be considered at signalized intersections with very high pedestrian/bicycle volumes, e.g. in an urban business district. 40% 100% High 20 S20PB Install advance stop bar before crosswalk (Bicycle Box) Signalized Intersections with a marked crossing, where significant bicycle and/or pedestrians volumes are known to occur.
15% 100% Very High
21 S21PB Modify signal phasing to implement a Leading Pedestrian Interval (LPI) Addition of LPI gives pedestrians the opportunity to enter an intersection 3-7 seconds before vehicles are given a green indication; only minor signal timing alteration is required. 60% 100% Very High

However, all-way stop control is suitable only at intersections with moderate,and relatively balanced volume levels on the intersection approaches. Under other conditions, the use of all-way stop control may create unnecessary delays and aggressive driver behavior. 50% 100% High

Typical improvements include "Stop Ahead" markings and the addition of centerlines and stop bars 25% 100% Very High 8 NS08 Install Flashing Beacons at Stop-Controlled Intersections Flashing beacons can reinforce driver awareness of the Non-Signalized intersection control and can help mitigate patterns of right-angle crashes related to stop sign violations. Post-mounted advanced flashing beacons or overhead flashing beacons can be used at stop-controlled intersections to supplement and call driver attention to stop signs. 15% 100% High

12 NS12 Improve pavement friction (High Friction Surface Treatments) Non-signalized Intersections noted as having crashes on wet pavements or under dry conditions when the pavement friction available is significantly less than needed for the actual roadway approach speeds. This treatment is intended to target locations where skidding and failure to stop is determined to be a problem in wet or dry conditions and the target vehicle is unable to stop due to insufficient skid resistance. 55% 100% Medium
13 NS13 Install splitter-islands on the minor road approaches The installation of a splitter island allows for the addition of a stop sign in the median to make the intersection more conspicuous.
40% 90% Medium
14 NS14 Install raised median on approaches (NS.I.)
Effective access management is key to improving safety at, and adjacent to, intersections. The number of intersection access points coupled with the speed differential between vehicles traveling along the roadway often contributes to crashes. Any access points within 250 feet upstream and downstream of an intersection are generally undesirable. 25% 90% Medium
15 NS15 Create directional median openings to allow (and restrict) left-turns and u-turns (NS.I.) Crashes related to turning maneuvers include angle, rear-end, pedestrian, and sideswipe (involving opposing left turns) type crashes. If any of these crash types are an issue at an intersection, restriction or elimination of the turning maneuver may be the best way to improve the safety of the intersection. 50% 90% Medium 16 NS16 Reduced Left-Turn Conflict Intersections (NS.I.) Reduced left-turn conflict intersections are geometric designs that alter how left-turn movements occur in order to simplify decisions and minimize the potential for related crashes. 50% 90% Medium
17 NS17 Install right-turn lane (NS.I.)
Many collisions at unsignalized intersections are related to right-turn maneuvers. A key strategy for minimizing such collisions is to provide exclusive right-turn lanes, particularly on high-volume and high-speed major-road approaches. When considering new right-turn lanes, potential impacts to non-motorized users should be considered and mitigated as appropriate. 20% 90% Low
18 NS18 Install left-turn lane (where no left-turn lane exists) Many collisions at unsignalized intersections are related to left-turn maneuvers. A key strategy for minimizing such collisions is to provide exclusive left-turn lanes, particularly on high-volume and high-speed major-road approaches. When considering new left-turn lanes, potential impacts to non-motorized users should be considered and mitigated as appropriate. 35% 90% Low
19 NS19PB Install raised medians (refuge islands)
Intersections that have a long pedestrian crossing distance, a higher number of pedestrians, or a crash history.
Raised medians decrease the level of exposure for pedestrians and allow pedestrians to concentrate on (or cross) only one direction of traffic at a time. 45% 90% Medium 20 NS20PB Install pedestrian crossing at uncontrolled locations (signs and markings only) Non-signalized intersections without a marked crossing, where pedestrians are known to be crossing intersections that involve significant vehicular traffic. They are especially important at school crossings and intersections with right and/or left turns pockets. See Zegeer study (Safety Effects of Marked vs. Unmarked Crosswalks at Uncontrolled Locations) for additional guidance regarding when to install a marked crosswalk. 25% 100% High
21 NS21PB Install/upgrade pedestrian crossing at uncontrolled locations (with enhanced safety features) Non-signalized intersections where pedestrians are known to be crossing intersections that involve significant vehicular traffic. They are especially important at school crossings and intersections with turn pockets.flashing beacons, curb extensions, advanced "stop" or "yield" markings, and other safety features should be added to complement the standard crossing elements. 35% 100% Medium 22 NS22PB Install Rectangular Rapid Flashing Beacon (RRFB) Rectangular Rapid Flashing Beacon (RRFB) includes pedestrian-activated flashing lights and additional signage that enhance the visibility of marked crosswalks and alert motorists to pedestrian crossings. It uses an irregular flash pattern that is similar to emergency flashers on police vehicles. RRFBs are installed at unsignalized intersections and mid-block pedestrian crossings. 35% 100% Medium 23 NS23PB Install Pedestrian Signal (including Pedestrian Hybrid Beacon (HAWK)) Intersections noted as having a history of pedestrian vs. vehicle crashes and in areas where the likelihood of the pedestrian presence is high. Corridors should also be assessed to determine if there are adequate safe opportunities for non-motorists to cross and if a pedestrian signal, or a Pedestrian Hybrid Beacon (PHB) (also called High-Intensity Activated crossWalK beacon (HAWK)) are needed to provide an active warning to motorists when a pedestrian is in the crosswalk.

CM Toolbox for Roadway Segments
Sr. No. Code Countermeasure Name CM Description CRF Federal Funding Systemic Approach Opportunity 1 R01 Add Segment Lighting Provision of lighting along roadways. 35% 100% Medium 2 R02 Remove or relocate fixed objects outside of Clear Recovery Zone Known locations or roadway segments prone to collisions with fixed objects such as utility poles, drainage structures, trees, and other fixed objects, such as the outside of a curve, end of lane drops, and in traffic islands. A clear recovery zone should be developed on every roadway, as space is available. In situations where public right- of-way is limited, steps should be taken to request assistance from property owners, as appropriate. 35% 90% High 3 R03 Install Median Barrier
Areas where crash history indicates drivers are unintentionally crossing the median and the cross-overs are resulting in high severity crashes. The installation of median barriers can increase the number of PDO and non- severe injuries. The net result in safety from this countermeasure is connected more to reducing the severity of crashes not the number of crashes. 25% 100% Medium
4 R04 Install Guardrail
Guardrail is installed to reduce the severity of lane departure crashes. However, guardrail can reduce crash severity only for those conditions where striking the guardrail is less severe than going down an embankment or striking a fixed object. Guardrail should only be installed where it is clear that crash severity will be reduced, or there is a history of run-off-the-road crashes at a given location that have resulted in severe crashes. 25% 100% High 5 R05 Install impact attenuators
Impact attenuators are typically used to shield rigid roadside objects such as concrete barrier ends, steel guardrail ends and bridge pillars from oncoming automobiles. Attenuators should only be installed where it is impractical for the objects to be removed. 25% 100% High
